“In this fiscal year, SeaChange’s net income grew by 79% and our revenues reached a record $157 million,” said Bill Styslinger, president and CEO, SeaChange International. “SeaChange significantly extended its leadership in on-demand television and today is responsible for more commercial deployments than any other VOD provider. We’ve shipped 1.4 million VOD streams, far more than our nearest competitor; however, our true differentiation is marked by our core competencies in storage, software and systems integration.

“In the course of the year, many of our cable customers in North America have expanded the depth and breadth of their VOD services, and SeaChange systems are some of the first to provide new utilities for our customers such as High-Definition TV on-demand and recording of broadcast programs,” said Styslinger.

“Over the past year, SeaChange has broadened its markets,” said Styslinger. “A year ago we had one telco customer; today we have eight, including such companies as Verizon and Japan’s NTT. Our international cable customers are in Asia, Europe and Latin America and have increased from two to 14. We have successfully broadened our opportunities and intend to build on our competitive advantages in software and media storage for the wide range of service providers, broadcasters and other content sources worldwide.”
